The last row of the table is misleading -- JSON spec has escape sequences, so the string is the same in all cells, but is expressed differently in JSON.

Indeed. Adding ensure_ascii=False to json.dumps() should eliminates the difference.

(As of YAML 1.2, it's officially intended that all valid JSON can be parsed as valid YAML.)

Sorry about that.
